Application filed November 26, 1907. Serial No. 403,95.

To all whom it may concern.'

Be it known that we, OSCAR DAMON and WiLLiAM L. SHOUP, citizens ol the United States, residing at Langdon, in the county of Reno, State ol Kansas, have invented certain new and useful improvements in Automatic Gil-Cups; and we do hereby declare the following to he a full, clear, and exact description oi" the invention, such will'enable others skilled in the art to which it apperainsto make and use the saine.

'lf' his invention designed to he attached to the huh of a vehicle wheel and other devi ees where it is necessary that the spindle on which the wheel turns should be kept constantly lubricated.

Furthermore, the invention consists of iinpio'venients in lubricators that are automatic in their action.

lt is the object of the invention to provide in'iprovements that will he entirely eflicient, simple in their organization, ready of attachment and other manipulations and certain in their action or inode of operation.

The nature is clearly shown iii the annexed drawings harming a part of this specification and to which reference is made.

(lt the said drawings-Figure l is a vertical eoitral sectional view of a feed-cup showing our improved appliances. Fig. 2 is a horizontal view, taken in the plane T2 2, ofY

Fie l.

by. n a u Similar reference ch aractcrs designate similar parts or features, as the case may be,

wherever they occur.

ln carrying out the invention we provide a suitable oil-cup, l, which it may be desirable to equip with a conical cap, 2, that may be provided with a supply hole, il, closed by a suitable air-tight plug, 4. rlhe parts and features mentioned may he differently shaped or arranged, so long as they are suited to the improvements. i

5 designates the feed-pipe in the oil-cup and having a hole, in its side as near the top as may be practicable to 'receive oil from the cup and convoy it to the spindle of the wagon to be lubricated.

The oil-tube 5 extends below the bottom of the cup and its lower end is threaded, as at 8, to permit it lo he tapped into the 1mb.

i 'lhe leed-pipe is screw-threaded at its upper end portion 9 to receive a thimble 10, thereon to be screwed up and down on the pipe to regulate the size of the hole 6, near the top, in a well-known way, and thus regulating the amount of oil supplied toathe tube. vPlaced Within the oil in the feed-tube 5 is a plunger-rod consisting of a rod of steel or other suitable material having formed thereon throughout its length a series'of hollow cones or conical cups opening downwardly.

As the wheel of the wagon turns on'its spindle, the cup `will be inverted and the plunger will drop by the operation of gravity to the outer end of the tube 5 into which the oil runs through the opening 6 and floods the rod, and as the Wheel continues its rotation and the cup is brought around to a vertical position again the rod again drops to the inner end of the tube and against the journal, each cup carrying a small quantity of the oil whichit deposits upon the journal, and this actionu's repeated at each revolution of the wheel. By this means a small quantity of the oil is positively carried from the oil cup to the journal at each revolution of the wheel, and waste and flooding of the journal thus avoided` The improved device is simple in construction, can be inexpensively manufactured and adapted to VAall the diilerent varieties of wheels orlother. devices which rotate upon a stationary journal, but as above stated,l is more particularly designed for use upon vehicle hubs.v i

What is claimed is 1. A plunger for the tubes of lubricating cups consisting of a rod having formed thereon a series of hollow concs.

2. The combinationwith a wheel and its spindle, of a lubricating cup having a feed tube communicating with the spindle, and a plunger operating in the tube and consisting of a rod having formed thereon a series of hollow cones. l

ln testimony whereof, we allx our signatures, in presence of two witnesses.
